So reading the many questions regarding the Czech Republic and using the train system, I see two sites to purchase tickets; IDOS.cz and CD.cz. Can someone explain the difference please? Or does it matter?
Wanting to make sure we get from Prague's airport to the train terminal. Would we take a bus from the airport to the train station?
And when purchasing the train tickets, can one sit anywhere on the train, or is there assigned seats/cars?
Thanks
